| 中文摘要 |
| 以江西省1:25万地形数据库为原数据,在详细的系统分析、模式比较基础上,设计开发了"江西赣江流域环境数据发布WebGIS系统".在系统设计上,采用了一种新的混合模式策略;在开发中,利用了MapObjects控件的GIS数据分析功能,及其组件MOIMS的地图服务功能.用户在客户端通过网页浏览器不仅可以实现放大、缩小、漫游等基本GIS功能,而且还可以制作专题图和通过属性值查询空间对象.该系统的应用,扩大了GIS系统的用户范围,使GIS的操作简单化,可辅助环境管理和决策. |
| 英文摘要 |
| ‘Environmental WebGIS system for Ganjiang Watershed', based on 1∶250 000 topographic spatial database and environmental database of Jiangxi province, was developed. In the system, a hybrid strategy was adopted. And the GIS analysis functions of MapObjects and Map server functions of MOIMS were integrated in the system. Users can use GIS functions, such as zooming in, zooming out, panning, making theme maps, finding geographic objects by environmental attribute values etc., through web browser on the client computers. With the application of the WebGIS system, expanding the GIS users' range, making the GIS operation easily, and assistanting environmental management and decision can be completed. |
